Abstract: A paging indication method, apparatus, and system are provided, which relate to the field of communications technologies, to solve a problem that power consumption of UE is high because the UE blindly detects a PDCCH periodically. A specific solution includes: receiving, by UE, indication information from a network side device, where the indication information is used to indicate a detection parameter used by the UE to detect a paging message, and the detection parameter is used to determine a detection manner used by the UE to detect the paging message; and determining the detection manner based on the detection parameter. The embodiments of the present invention are applied to a process in which the UE determines a detection manner used to detect the paging message.
